September at Horkans: Kickstarting the Autumn Season.
Posted by Paraic Horkan
September is nature’s time for renewal; a wonderful season to sow, feed, and ready your garden for spring. With a little nurturing this month, you’ll ensure your garden brims with colour and life through autumn and into next spring. Let Paraic guide your way.
Lawn Care
- Remove moss now with Zero Lawn Moss; it starts working overnight.
- Feed lawn 24 hours later using Zero Lawn Feed for nourishing growth and moss prevention.
- Reseed bare patches or sow a new lawn with Green Velvet lawn seed; ideal while the ground’s still warm.
Sow & Grow
- Sow seeds of edibles and flowers now; pop into compost, cover with cling film, and replant when they shoot.
- Plant Japanese onion sets for early spring shoots and full bulbs come April–May.
- Plant autumn and winter veggies like winter cabbage, Chinese cabbage, purple sprouting broccoli, lettuce, and iceberg lettuce.
- Add berrying trees like Malus (crabapple) now; colourful berries in autumn and beautiful blossoms in spring, plus great for wildlife.

Garden Care
Control algae and moss on hard surfaces with PAC; apply on a dry, calm day and see it vanish in 7 days.
Before
After


Apply through a watering can or pressure sprayer on a dry calm day to the hard surface area and watch the moss and algae disappear in no time.
Add Some Garden Colour
- Start a wildflower patch; September is ideal for sowing seeds or bulbs for spring and summer blooms.
- Plant winter-flowering cyclamen, pansies, violas, heather, and aconites in pots and window boxes for early seasonal colour.
- Add evergreen climbers: virginia creeper, hydrangea, honeysuckle, ivies; to brighten garden with foliage and blooms.
- Propagate shrubs by taking pencil-length cuttings, dipping in rooting powder, planting in perlite mix, and covering with polythene to root on a bright window sill.

Wild Garden Birds
- Feed your feathered friends with high-energy options: sunflower seeds, fat balls, wild bird mixes; to help them build reserves for winter.
- Clean out old nests from nesting boxes now, ready for future use.

Why These Actions Matter
- A moss-free, fed lawn now sets you up for lush green grass next spring.
- Sowing and planting today builds your harvest and displays for winter and beyond.
- Adding climbers and wildflowers keeps your garden rich in colour and buzzing with wildlife.
- Nourishing the birds supports nature in your garden; what a joy to watch them through the colder months.
Friendly Reminders from the Team
